摘要：
A method and system for cache optimization in a hybrid solid state drive and magnetic storage cache architecture for a content delivery network (CDN) is disclosed. The CDN has a number of geographically distributed points of presence (POPs) across the Internet. Customers of the CDN pay for storage of content objects. Cache management in a POP analyzes information related to content objects to determine if storage will be on a solid state drive (SSD) instead of a magnetic drive. The information used in this analysis is from the application layer or above in the open systems interconnection (OSI) model. The content objects are delivered from either the SSD or magnetic storage to end users.
